Follow-up on this, we are booked on Grandeur for 16 night on a Panama crossing in Dec.
Even though it is a long-ish voyage, would we still be limited to one reservation in each for the entire cruise? in other words, it's definitely based on "segment" rather that cruise length....
I know there is potential for drop-ins, but I'm a bit concerned as our first Regent experience (11 nights in French Polynesia in late 2019), I couldn't get a second night in Prime 7 no matter what I tried.
